- What are the four basic assumptions of perfect competition? Explain in words what they imply for a perfectly competitive firm.arrow_forwardA9 The characteristics of a "perfectly competitive" market require that there is 1) a large number of firms, 2) producing products that are identical across firms, 3) in an industry where there are no barriers to entry. It's unlikely that any industry accurately reflects these extreme assumptions, but what industries can you think of that do display these characteristics at least to some extent? Try to identify the limits of your example in reflecting "perfect" competition.arrow_forward1.
